I try to do a base download and it fails immediately. Is there something i've done wrong?
I uninstalled UWUVCI and did a fresh reinstall.
I'm assuming you mean UInjectForge (UIF). UIF doesn't need to be installed, so all you have to do is delete the folder that you downloaded and open up the new one. Did you do anything else to "uninstall" the program? A user mentioned that they deleted their AppData folder for UIF, and then the program started acting weird. They stated once they deleted their workspace folder (you can figure this out by going to Utilities -> "Settings and Storage" -> "Storage") it made the program work properly again.
I see the confusion, so this is a completely different tool, I migrated everyone who bought my fork of UWUVCI to this program which I made completely from scratch. I didn't even think about using the itch.io launcher to download this program, so I should see if maybe that's getting in the way. Could you possibly share your log file or something so I can have an idea of what the issue is? Without an error message, I'm basically looking around in the dark.
